    2-INSTALLATION INSTRUCT The requirements in this chapter refer to the regulations of the Italian installation Standard UNI 10683. In any case, always comply with the regulations in force in the country of installation. PELLETS Wood pellets are obtained from compressing sawdust produced during the processing of natural dried wood (without paint). The compactness of the material is guaranteed by the lignin contained in the wood itself and allows pellets to be produced without glue or binders.
  • Page 8 2-INSTALLATION INSTRUCT PRECAUTIONS REGARDING INSTALLATION IMPORTANT! Product installation and assembly must be carried out by qualified personnel. The product must be installed in a suitable place for it to be regularly opened and routine maintenance to be performed. The environment must be: • Compliant for proper operation.

  • Page 10 2-INSTALLATION INSTRUCT CONNECTION OF THE SMOKE EXHAUST DUCT When drilling the hole for the smoke exhaust pipe, the possible presence of flammable materials must be considered. If the hole must be made through a wooden wall or thermolabile material, the INSTALLER MUST first use the relative wall fitting (minimum diam. 13 cm) and adequately insulate the pipe of the product that passes through it, using suitable insulating material (1.3 - 5 cm thick with minimum thermal conductivity 0.07 W/m°K).
  • Page 11 2-INSTALLATION INSTRUCT Always use pipes and fittings with appropriate seals that guarantee tightness. It must be possible to inspect all sections of the flue duct and they must be removable for periodic internal cleaning (T-fitting with inspection hole). Position the product considering all the above requirements and instructions. IMPORTANT! The following conditions must be complied with when connecting the appliance to the chimney: • ...
  • Page 12 2-INSTALLATION INSTRUCT CONNECTION TO THE EXTERNAL AIR INTAKE It is essential for the room where the product is installed to be adequately ventilated in order to guarantee sufficient air for proper combustion in the appliance. This is possible by means of suitable ventilation openings in the room itself or in an interconnected room through a permanent opening between the rooms (room ventilation is excluded in the case of installation with Oyster technology, where combustion air is ducted directly from outside).

  • Page 14 2-INSTALLATION INSTRUCT OPERATING PROBLEMS RELATED TO DRAUGHT DEFECTS IN THE CHIMNEY Among all the weather and geographical conditions that affect chimney operation (rain, fog, snow, altitude a.s.l., exposure to sunlight, orientation to the cardinal points, etc.), the wind is certainly the most determinant. In fact, besides the thermal depression caused by the difference in temperature between inside and outside the chimney, there is another type of depression (or overpressure): dynamic pressure caused by the wind.

Once the connections are complete, assemble the cladding (ceramic or serpentine sides). If the product must be connected to an exhaust pipe that goes through the rear wall (to enter the chimney), make sure not to force it in. Adjust the 4 feet (J) to level the stove for the smoke exhaust and the pipe to be coaxial.
  • Page 21 3-INSTALLATION AND ASSEMBLY CONNECTION OF THE SMOKE OUTLET PIPE You can choose whether to release the smoke on the rear part or upper part of the product.
